BO BBIN-CARRIER FOR BRAlDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 415,311, dated November19, 1889.

Application filed July 5, 1888. Serial No. 279,120- (No model.)

To all whom it may concern.-

Be it known that I, BENOIT ORIOL, a citizen of the Republic of France,and a resident of St. Chamond, in the Department of Loire, FrenchRepublic, have invented certain new and useful Improvements inBobbin-Carriers for Braiding-Machines, of which the following is aspecification.

My invention relates to improvements in bobbin-carriers forbraiding-machines; and the object of the same is to secure a regularunwinding of the thread from the bobbin when the machine is running athigh speed, and consequently to'increase the output of thebraiding-machine.

The bobbin-carriers heretofore made are limited to a certain speed,which cannot be exceeded on account of the resistance caused by thefriction between the bobbin and the bobbin-carrier and the danger ofbreaking the thread as often as the limited speed is surpassed. In orderto meet such difficulty,

the bobbin should be made to facilitate thev delivery of the thread assoon as a certain tension of the thread is reached. I attain this objectby the mechanism illustrated in the accompanying drawings, in whichFigure 1 is a side view of the bobbin-carrier with the bobbin; Fig. 2, aback view, and Fig. 3 a top view of the same; while Fig. 4 representsthree different views of a detail hereinafter referred to.

Similarletters refer to si milar parts throughout the several views.

The lever L, controlling the rotation of the bobbin upon the hollowbobbin-carrier, is pivoted at a to the upright arm n, attached to thesaid carrier, and engages the screw-thread of a collar D,.resting uponand secured to the top of the bobbin B. As soon as the bobbin-thread fcommences to elevate the tension-weight p, and the tension of the threadexceeds a certain limit, the arm e of the usual catch-lever E tends toturn the regulatinglever L into the position illustrated by the dottedline 2. By this movement the point of the regulating-lever L acts uponthe screwthreads of the collar D, the pitch of the screwthreadcorresponding with that of the teeth 0 of the collar, and thus causingthe latter to turn with the bobbin in the direction of the unwinding ofthe thread. Herefrom it results that the whole resistance the bobbinoffers to the rotation ceases at the moment where usually it would bethe greatest, and this result is effected without causing the thread toovercome a force capable of breaking it, in order to cause the play ofthe regulating-lever, which then occupies its original position, whilethe catch-lever drops again. At this instant the regulating-lever Lcannot turn the bobbin backward, because its point rides upon the upperface of the screwthreads of the collar D, until it meets a groove of thethread, which will allow the lever L to drop into position to again actupon the collar D and the bobbin B when the tension of the bobbin-threadagain exceeds the limits of the desired tension.

Another reason of the resistance of the bobbin to its proper rotation iscaused by the circumstance that the thread is not drawn offperpendicularly from the bobbin. To effect this, a weighted thread-guideG, guided in its reciprocations by its projection 2, within the verticalslot of the upright arm n within the bow m, is carried by the thread fof the bobbin to that position where the thread is drawn offperpendicularly to the axis of the bobbin. The thread passes direct fromthe bobbin B, through the slot u, around the stay 2' in the slidingthread guide G, thence upward through the eye in the top of the uprightarm n, downward through an eye in the catchlever E, thence through aneye in the upper end of the tension-rod p and up through the eye in thetop of the bobbin-carrier. The weight of the sliding thread-guide G issuch as to maintain the thread always at right angles to the bobbinwhile unwinding, thus insuring a more smooth and uniform unwinding ofthe thread from 01f the bobbin.

As all other parts of the bobbin-carrier and their action are generallyknown, they do not require further explanation, inasmuch as they do notform essential. features to carry my invention into effect. I thereforedo not claim the construction of the bobbin-carrier, broad- 1y; but

What I do claim, and desire to protect by Letters Patent, is-
